Hi Ben and welcome to the forum,
That is an excellent question! As you have found out you can select 5.1 audio when producing a DVD, BRD and AVCHD discs but there is no ability to apply any audio mixing to the separate audio tracks during pre-production that I am aware of. It has been requested in future releases of Power Director by other members here, but for now I don't think it is possible. You would think that it should be an available feature? I am not exactly sure why it is not included.
It might be possible to edit your audio in another audio editing software, but I have never tried it myself and I can't offer you any alternatives. Maybe someone else will chime in with a solution for you.
